Abstract

We have succeeded in generation of micro-bubble ring in microfluidic environment. High speed ejection of electrically driven mono-dispersed micro-bubbles enables to penetrate mother bubble, which forces to produce circulating motion in the bubble, and bubble rings are successfully produced. This is the new protocol to produce bubble ring in microfluidic environment for the first time. This micro-bubble ring carries a strong vortex characteristic which can contribute to efficient mixing in closed micro-space and also cleaning of micro-channel wall.
